The aim of this study is to evaluate how much would the building energy consumption be saved by applying DSSC BIPV window which is possible to control the transmittance and express the color in the office building. For this, physical characteristics such as transmittance and reflectance, U-factor of DSSC areanalyzed and an annual energy consumption that is connected to dimming control is calculated when DSSC BIPV window is applied by alternate clear window system. As a result, It is possible to reduce the anannual energy consumption as much as4.1% by just change the clear double window system to DSSC BIPV double window system because the major factor to reduce energy consumption in the office that has much cooling load than other building is SHGC. When the thermal insulation properties of DSSC BIPV window with low-e coating and making triple window are improved, energy saving ratio is about 9%. Plus, energy saving ratio of 25~28% in lighting energy consumption is possible when the dimming control system with DSSC BIPV window is adopt.

SAR(Synthetic Aperture Radar)는 radio wave를 이용하여 영상 정보를 얻는 Radar이다. Platform이 radio wave를 방사하여, 대상 물체에서 되돌아오는 후방 산란파 (Back-scattering) 신호를 거리에 따라 2차원 영상(SAR image)으로 기록하여 지형도를 작성한다. 본 논문에서는 SAR image 복구를 위해 SAR image processing에서 다양한 window를 적용하는 시뮬레이션을 통하여 window의 적용 효과를 연구하였으며, 그 결과 신호의 SNR 측면에서는 Flattop window가 가장 좋은 성능 향상을 보여 주는 것을 확인하였다.

채광과 직사광 제어라는 자연조명의 상반된 목적을 동시에 충족시키기 위하여 본 연구에서 기존의 유리 창호를 용도와 기능에 따라 채광창과 조망창의 두 부분으로 분리한 이중분할창호시스템이 설계되었다. 채광량을 극대화하기 위하여 고창부의 채광창은 투명유리를 사용하며 조망창은 제어를 위한 다양한 기능성 유리를 적용하였다. 부가적으로 물리적 광제어 및 조절장치인 광선반, 수평 및 수직형 블라인드가 내장된 일체형 이중분할창호를 포함한 포괄적인 광제어 기법의 양적$\cdot$질적 조명효과를 통합적으로 평가하여, 제안된 창호시스템의 적용성을 평가하였다. 조망창과 채광고창의 경계부에 수평형 광선반을 설치하면 일차적인 직사광 유입으로 인하여 극심하게 높은 조도를 나타내는 창면 관접부의 조도를 완화시키는 차폐효과와 아울러 광선반의 반사 능력으로 인하여 채광성능면에서 불리한 실내측 후면부의 조도를 증가시키는데 현격한 효과를 2차적으로 기대할 수 있다. 실내바닥 수평면의 평균조도는 차광기능에 의하여 균제도가 2배 이상 향상되며 수평 슬릿의 반사에 의하여 $16(\%)$ 이상 증가하는 효과가 있으며 태양고도가 낮고 방위각이 정남향이 아닌 경우 수직 차광재를 사용하면 광제어 기능으로 인한 균제도의 향상과 $10(\%)$이상의 후면부 조도의 증가 및 조망이 확보되는 상대적인 장점이 있다.

A derivative of 1,4-Naphthoquinone coded HBU671 was synthesized and used in addition to activated carbon as composite electrode for supercapacitor application. From the electrochemical properties analysis, a specific capacitance of about $300F\;g^{-1}$ exhibited almost two times of that of activated carbon at a scan rate of $100mV\;s^{-1}$ and a potential window of - 0.2 - 1V. This improvement is due to the inherent redox reaction in HBU671. Cycle test also proved that this composite is still stable even after 1000 cycle within the applied potential window and it is highly recommended for practical application.

Smart windows are capable of varying their visible light transmittance (VLT) in response to changing environmental conditions. The VLT variability of architectural windows is highly valuable because it enables indoor lighting and energy environments to align with external changes. However, challenges such as high installation costs and assurance of glass visibility have prompted the exploration of alternative solutions, including models incorporating partially applied smart windows., Prior research focused on useful daylight illuminance (UDI) analysis for south-facing office buildings, pointing out suitable areas for smart-window implementation to enhance lighting control. In this study, we broadened this scope by determining optimal smart-window application zones under changing building orientation. Furthermore, we studied the correlation between building orientation and smart-window deployment areas.

The apartment will be much more convenient than the other one in the application of green technologies, providing the merits by mass production. For example, pre-manufactured building materials can be effectively adapted to the formation of buildings. Recently, the form of double-enveloped window system has been developed for the purposed of minimizing energy loss occurred around windows. On the other hand, the expansion of balcony area was legalized and thus, a visual buffer area does not exist any more. All-glass window wall on apartment houses without a balcony produces pretty harmful area with direct sunbeam. A various types of glass can be applied to the window system and it plays a critical role in the determination of inner visual environment. For the purpose of verifying the potential of its daylighting, a mock-up model has been constructed and tested. The refurbished version of conventional window shows its illuminated characteristics. Clear and Low-e glass have been adapted for window area and daylighting ratio has been compared in both test cells.

The purpose of the paper is to analyze situations and its prospect of Single Window System for custom's one-stop service in Japan and to suggest effective application was to improve of in Korea's Customs systems. In response to the growing demand for lower trading costs and shorter and more predictable lead times with the advancement of the international trade supply chain, the Single Window System for import/export and port-related procedures was launched on 23 July 2003 in Japan. The concept of the Single Window System is to establish a comprehensive computer interface system that enables users to complete all import/export and port-related procedures required under different laws and regulations in a single input and single transmission. To realize the concept, the data elements and submission times of the various systems were harmonized, and manual procedures, such as quarantine and immigration, were computerized. Then, all the necessary systems, such as NACCS, Port EDI System, and Crew Landing Permit Support System, were interconnected as a Single Window System. Close cooperation among other governmental organizations and the private sector was a key factor in the successful development and smooth utilization of the System so that it fully met all parties' needs. It is anticipated that operating costs will be greatly reduced and trade facilitation will be enhanced as a result of the simplification of procedures. Korea Customs advocates the Single Window System as a best practice at ASEAN and WCO to contribute to the development of regional and international capacity building.

Using sealant for window installation is sealing the gap between the window frame and outer wall (such as concrete). A sealant serves to prevent external environmental impacts such as moisture, rain, sand, and dust entering inside of the building and make the building durable. In order to fulfill basic jointing function of sealing, at least 6 mm joint gap between two bonding surfaces are required. Also, adhesion performance between sealant and surfaces and the compatibility with other building materials are required to check before installation. In general, 2 part polyurethane sealant and 1 part silicone sealant are most common materials for sealing the joint of window. In this study, adhesion performances of those two generic sealants reflecting actual application conditions and the compatibility evaluations with other building materials are conducted to propose proper window installation procedures.
